Intelligent light-sensitive stereo

Abstract

The invention discloses an intelligent light-sensitive stereo. The intelligent light-sensitive stereo comprises a box body, an operation and LED (Light Emitting Diode) display unit, a control panel, a power supply unit, an amplifying unit, an audio signal input unit and a horn unit, wherein the operation and LED display unit, the control panel, the power supply unit, the amplifying unit and the audio signal input unit are arranged on the box body, the horn unit is connected with the outer part of the box body, a light sensor input unit is mounted at the bottom of a front panel of the box body, an MCU (Micro-processor Control Unit) is mounted in the middle of the front panel, and an A / D (Analog-to-Digital) conversion unit is arranged in the central region in the box body; the color and brightness of ambient light surrounding the stereo are collected by the light sensor input unit and transmitted to the A / D conversion unit which is electrically connected with the light sensor input unit; corresponding digital information is converted and transmitted to the MCU electrically connected with the A / D conversion unit by the A / D conversion unit; the digital information is received by the MCU, a corresponding regulating scheme is invoked through different light-sensitive data and calculation, and the sound field mode and the volume of the stereo are automatically regulated.

Description

technical field [0001] The invention relates to an audio device, in particular to a light-sensing intelligent audio system. Background technique [0002] The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. It is an extremely important part of the audio system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly to. It has to deal directly with human hearing, which is very sensitive. And it has a strong ability to distinguish the timbre of complex sounds. Since the human ear's subjective experience of sound is the most important criterion for evaluating the sound quality of an audio system, it can be considered that the performance of the speaker plays a key role in the playback quality of an audio system. [0003] Under different environmental conditions (color and brightness of light),...
